Answer:
m∠3 = 2x - 10° and m∠6 = 3x + 20
 m∠3 = 58°          ;    m ∠6 = 122°
Step-by-step explanation:
a ║ b
m∠2 = m∠6                     If ║ cut by a transversal, then corresponding angles 
                                          are ≅ and =
m∠7 = m∠3                   If ║ cut by a transversal, then corresponding angles
                                        are ≅ and =
m∠2 = 3x + 20              Given
m∠7 = 2x - 10                 Given    
m∠6 + m∠3 = 180°         If ║ cut by a transversal, then each pair of same-side
                                        interior angles (also called consecutive interior angles
                                        are supplementary (sum = 180°) .     
3x + 20 + 2x - 10 = 180°
 5x + 10 = 180°
5x = 170°
x = 34°
Answer:   m∠3 = 2x - 10° and m∠6 = 3x + 20
                 m∠3 = 2(34) - 10  ;    m∠6 = 3(34) + 20
                  m∠3 = 58°          ;    m ∠6 = 122°
                                  
 
        
             
        
        
        
That's the easily recognizable factored form of 
the difference between two squares. Before
factoring, it was
x² - 16 .
